Seabury Capital Management
Seabury Capital Group operates as the investment holding company of founder John E. Luth, deploying proprietary capital alongside fee-generating advisory and investment banking services. Since 1995, the firm has structured itself around aviation and aerospace verticals, fielding professionals across more than 20 countries. Its client advisory track record includes over 5,000 engagements for more than 400 clients, covering $350 billion in restructured or raised financing and over $450 billion in new aircraft orders (per firm website). The firm's investment portfolio spans aviation, aerospace & defense, logistics, travel, and financial technology. Seabury Capital Management LLC — a newly incorporated fund manager — is slated to launch specialized investment funds in aviation, travel, and technology during 2025, formalizing what has historically been a balance-sheet venture arm. The firm anchors deep-tech venture funds like Aero X Ventures, which launched Fund II to invest in aviation and defense startups (per firm website). Financial asset management and trade finance are housed under Seabury Asset Management LLC, adding credit and liquidity strategies to the mix. Seabury Capital reports holding over $1.3 billion in investment assets as of year-end 2024, managed across dedicated vehicles. The firm's geographic reach includes offices in New York, London, Los Angeles, and Houston, with professionals active on five continents. In addition to its venture and asset management arms, the firm operates FINRA-, NFA-, and FCA-regulated investment banking units in the U.S. and U.K., delivering restructuring and capital-raising mandates to external aviation and aerospace clients. The structural differentiator is Seabury's dual posture as both a proprietary capital allocator and a regulated investment bank. The firm earns fees advising airlines and aerospace companies on restructurings and fleet orders, while simultaneously investing its own balance sheet in the same sectors — a model that grants it transaction flow and sector intelligence rarely available to a conventional single-family office.
